In answer to the previous message: If he looks at todays synoptic chart he
will see that there is a trough extending out from the low pressure and
waving front over europe. This is enough to explain how some stations in the
north midlands have westerly winds while others futher south have a south
eaterly direction; I other words the winds are following the direction of
the isobars round the trough.
Hope this is helpfull!
